Within the past 10 years I've lost my sense of even the slightest security. Not as if that security ever existed in the first place, just that I was much less aware of the possibilities. I feel like the vulnerabilities that we've seen on Intel CPU's is just the tip of the iceberg. Maybe within a decade or two we'll see that no Intel CPU was ever safe and high level agencies have literally since the beginning had access to these vulnerabilities.
I mean some of the stuff we've seen is terrifying. Malware that infects the Management Engine of the Intel CPU that survives regardless of OS you install or hardware you change? I'm afraid these aren't even 1% of what is and has been capable since the beginning that we don't know about.
Multiple companies I've worked at have been in the position of their competitors suffering security breaches. In all instances there were communications sent to all staff not to speak externally pointing to the inident for publicity/promotion of our service. While you can't turn a blind eye, it's just not a good look. Besides, tomorrow it could always be you/your company.
Telegram has some positives, but the lack of e2e without secret chats is inexcusable--notnto mention secret chats' notifications are crippled (no option to see sender or message content.) If only Signal had working profile avatars instead of seeing some ancient Google+/Facebook/social media photo that sync'd to their contact list eons ago they didn't even know was there... Small UX things can make all the difference, haha.
